Is Anyone Using This Weather Site?

Has always worked pretty well for me.

I look at it for fun/reference, but never to dial the car. That is what a dedicated weather station is for. #Computech for me.

I have not used it so can not say how well it works.

It look like it uses the DynoJet SAE J1349 Dyno Correction factor as 100%. Most people will have had their engine on an engine dyno which uses SAE J607. Notice the DA = 1946 at 100% on this calculator. J607 at 100% is a DA = 0.

Not sure if I understand you, why would you use -90 for dew point.

As I now look at it again. I really should have used something lower. While I did get Relative Humidity to 0% and Vapor Pressure to 0 in Hg there was still 0.01 hPa Vapor Pressure.
